Oh no she didn’t!
I have to wonder what their clothing is made out of to be so sheer. It’s not linen (or maybe she was just commenting on the boring cut, not the boring cloth), but it seems unlikely to be silk unless there’s a Silk Road set up. Definitely not wool- too darn hot, and in order for it to be that transparent, it’d have to be lace. I did hear that the Egyptians invented knitting, though. It was found in a desert grave there, fun fact.
Perhaps cotton? /fabricnerd
